People are different from other primates, but not as different as they might like to think. It's true that there are significant contrasts in size and proportion between humans and other primates. And, of course, humans are by far the more intelligent. Nevertheless, to use chimpanzees as an example, both they and humans have the same muscles and bones, located in almost the same places and working in nearly the same ways. The internal organs of both animals are also very much alike, as are their blood and other body fluids. Seen under a microscope, even their genes are strikingly similar.
